Specification of Letters Patent.

Patented Jan.27,1914..

Application filed January 8, 1913. Serial No. 740,831.

To all whom it may concern:

Be it known that we, HUGH CooNnY and ORRIS E. VVIL'rsIE, citizens of theUnited States, residing at Marion, in the county of Grant and State ofIndiana, have invented new and useful Improvements in Tires, of whichthe following is a specification.

The invention provides a soft tread tire for vehicle wheels of everydescription including bicycles, motor-cycles and auto mobiles, said tirebeing constructed to utilize pneumatic pressure and the resiliency ofyieldable material such as rubber.

The invention provides a tire having a plurality of cups in its outer ortread 'side, said tire being reinforced by layers or strips of canvas orlike material, said strips being cemented together by rubber or securedin any manner to insure the provision of asubstantial and durablearticle.

The invention consists of the novel fea tures, details of constructionand combination of parts which hereinafter will be more particularly setforth, illustrated in the accompanying drawing, and pointed out in theappended claim.

Referring to the drawing, forming a part of the specification, Figure 1is a side view of a part of a tire embodying the invention, parts beingbroken away. Fig. 2 is a top plan view thereof. Fig. 3 is a section onthe line w a? of Fig. 1.

Corresponding and like parts are referred to in the followingdescription, and indicated in all the views of the drawing, by the samereference characters.

The numeral 1 designates a rim which forms a support for the tire properand this rim may be a part of the vehicle wheel or may be separatetherefrom and adapt-ed to be secured in place thereon. The rim 1 isprovided with side flanges 2 for retaining the tire in place thereon.

The tire is indicated at 3 and may be constructed wholly or in part ofrubber, but it is preferred to have the same embody reinforcing stripsof canvas or like material. The tire may be of any cross sectionaloutline and its tread side is broad so as to obtain an extended bearingupon the surface. A plurality of depressions 4 are formed in the outeror tread side of the tire and con stitute chambers or cups for receivingair to supplement the action of the tire in supporting the load and alsoto maintain a partial vacuum under certain conditions to preventskidding. The tire is reinforced around the depressions, chambers orcups 4, said reinforcement consisting of canvas or like materialencircling said depressions and having the layers cemented. Thesereinforcements are indicated at 5. The edges of the tire are alsoreinforced by circumferential strips 6 which are molded or otherwiselaid into the material forming the tire so as to strengthen the sameagainst circumferential expansion The inner ends of the depressions atare made rounding and receive washers 7 of plano-convex form, bolts orfastenings 8 being employed to secure the washers and the tire to therim 1, said bolts passing through openings formed in the washers, tireand rim.

From the foregoing description, taken in connection with theaccompanying drawing, the advantages of the construction and of themethod of operation will be readily apparent to those skilled in the artto which the invention appertains, and while we have described theprinciple of operation of the invention, together with the device whichwe now consider to be the best embodiment thereof, we desire to have itunderstood that the device shown is merely illustrative, and that suchchanges may be made when desired as are within the scope of the claimappended hereto.

Having thus described the invention what is claimed as new, is

A continuous tire of yieldable material having a plurality ofdepressions of cup form in its tread side, a reinforcement for each ofthe depressions consisting of ateXtile strip wound upon itself with thelayers cementedtogether and set in the body of the tire and forming apart thereof, and other strips molded in the edge portion of the tireupon opposite sides of the depressions therein.

In testimony whereof we aflix our signatures in presence of twowitnesses.
